Title: Method for self-synchronization of configurable elements of a programmable component
Inventor: MUENCH ROBERT
IPC: G06F15/78
Filed: 1998-02-07
Abstract: The invention relates to a method for synchronization and reconfiguration of configurable elements in components with two-dimensional or multidimensional programmable cell structure (DFP, FPGA, DPGA, RAW machine) as well as to the control of conditioned branches in common microprocessors, digital signal processors and microcontrollers. According to said method, synchronization signals are generated during processing within the data flow by the elements that are to be processed and configured by means of comparisons, algebraic signs, transmission of arithmetic operations, error status or the like, and are sent to additional elements for synchronization via the data bus.  Configuration words within a configurable element are generated from the data flow on the basis of corresponding commands and communicated, along with the address of the register to be picked up, to a further configurable element via the data bus, wherein said element is thus (re)configured without the influence of an external load logic. A valid configuration of the configurable elements from a plurality of configurations or a valid command from multiple possible commands of an arithmetic processing unit is then selected during running time on the basis of synchronization signals.

Title: Shaped charge for large diameter perforations
Inventor: HETZ AVIGDOR
IPC: F42B1/028
Filed: 1999-09-27
Abstract: A shaped charge for generating a large hole in material such as well casing downhole in a wellbore. A shaped charge liner is oriented about a longitudinal axis, and a disk is positioned at the liner apex. When an explosive material is initiated the liner collapses into a perforating jet. The disk alters the jet formation process and changes the shape and location of a bulge within the perforating jet. Consequently, the shape of the perforating jet retains a larger diameter for generating a larger hole in the material to be perforated or for controlling the penetration depth. The disk surfaces can be flat, concave, convex or other shapes, and the disk composition can be varied to accomplish different design criteria.

Inventor: GU CHUANG
IPC: H04N7/30
Filed: 1998-06-22
Abstract: A sprite generation method used in video coding generates a sprite from the video objects in the frames of a video sequence. The method estimates the motion (1200) between a video object in a current frame and a sprite constructed from video objects for previous frames. Specifically, the method computes motion coefficients of a 2D  transform that minimizes the intensity errors between pixels in the video object and corresponding pixels inside the sprite. The method uses the motion coefficients from the previous frame (1206) as a starting point to minimizing the intensity errors. After estimating the motion parameters for an object in the current frame, the method transforms the video object to the coordinate system of the sprite. The method blends (1204) the warped pixels (1202) of the video object with the pixels at corresponding positions in the sprite using rounding average such that each video object in the video sequence provides substantially the same contribution to the sprite.

Abstract: A method and system are provided for transmitting information from a faster network to a data terminal via a slower network connection. The invention is adapted for use with any Internet access device or terminal, such as an Internet-compatible telephone. A client connects to the Internet via an intermediary software program, known as the Gateway (GW). In the preferred embodiment of the invention, the GW executes on a host computer of an ISP's Local Area Network (LAN). The GW thus mediates the data transfer between the Internet, such as the Web, and the client Internet terminal. The GW employs a point-to-point Internet protocol, the Gateway Interface Protocol (GWIP) to communicate with the client over the low-bandwidth link. The invention shifts the entire overhead of the Internet protocol stack to the GW, and does not involve the Internet terminal or the slow link between Internet terminal and GW. The GW makes and negotiates multiple Internet requests, in parallel, and multiplexes the resulting data streams, allowing documents to be loaded in parallel with their associated images. The GW may also be used to conveniently customize or upgrade the Internet terminal. The GW performs off-line services and caches commonly used information fetched from the Internet. The invention is also readily adapted for use with Internet access devices that require different document formats.

Filed: 2000-09-06
Abstract: A signature scheme is provided in which a message is divided in to a first portion which is hidden and is recovered during verification, and a second portion which is visible and is required as input to the verification algorithm. A first signature component is generated by encrypting the first portion alone. An intermediate component is formed by combining the first component and the visible portion and cryptographically hashing them. A second signature component is then formed using the intermediate component and the signature comprises the first and second components with the visible portion. A verification of the signature combines a first component derived only from the hidden portion of the message with the visible portion and produces a hash of the combination. The computed hash is used together with publicly available information to generate a bit string corresponding to the hidden portion. If the required redundancy is present the signature is accepted and the message reconstructed from the recovered bit string and the visible portion.
